Toivonen is one of the young, new Finnish NHL-goaltending generation that includes Kari Lehtonen (Atlanta), Antero Niittymaki (Philadelphia) and Hannu Toivonen (Boston). After these guys, the upcoming names are Tuukka Rask (Toronto) and Karri Ramo (LA Kings).
On Toivonen's potential he was not that hyped when he played in Finland. Of course, he was quite young at the time. To my perspective Toivonen paddles down on his knees to much and is not quite there yet. Bruins goalie Tim Thomas was superb in Finnish Elite league and currently he has signed a new deal with the team. This means that Toivonen will have tough competition at least for the next couple of years.
